-26F in Cedar Rapids, Iowa this morning. Right now at noon it is -16F. That is the coldest I can remember it being mid-day. Usually we get radiational cooling to get the -20F temps, but wind was howling here as it was where @warmwxrules is.
It is supposed to be colder tomorrow: -31F is the forecast low.
No trees in my yard now, so nothing to be damaged. I hope the trees I moved last spring to a temporary site will survive since it is about 40 min south.
